Specification of Letters Patent.

Ya/tented April 1'7, 1906.

Applicationfiled September a, 1903. Serial No. 171,762.

in what are'known as .cushion-tires, and it relates more specifically to the particular class of cushion-tires in which aresilient core is inclosed in an outer casing and the whole suitably fastened to the felly or rim of the Wheel. y

The object 'of the present invention is to increase the resiliency of the tire and to secure it to the fell in such a manner as to avoid all danger o creeping or other dislocation of the tire.

This specification is an exact description of one example ofmy invention, while the claims define the actual scope thereof.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in both the views.

Figure 1 1s a perspectlve cross-section of the tire, showing it applied under pressure;.

and Fig. 2 is a similar View, excepting that the tire is here shown in its normal or noncompressed state.

(1 indicates the rim or felly of the wheel,

which is usually constructed of wood.

1) indicates an annular wooden strip, which is preferably made up of a-number of areshaped sections placed .around the outer circumference of the rim-section'c.

0 indicates the interior cushion, which is formed of rubber with a number of cells therein, as illustrated, and thenormal. shape of which is that shown in Fig. 2+ viz., a round ing outer portion running into a contracted or narrow base the width of which is just equal to that-of the annular strip b.

' d indicates .the outer casing of the tire,.

which is formed of rubber and canvas and conforms in alliessential particulars to the shape of the core 0, the outer or peripheral portion-of the casing being thicker than its side portions-for obvious reasons. The inner edges d .of the casing d project inward beyond the core 0 and alongside of the strip Zr, and said inner edges are provided. with wires 0, which extend completely around the tire and are embedded in the rubber and canvas forming the casing.

Fastened to each side of the run a are metallic clamp-platesf, which may be either sectional or continuous, as desired, and which are held in place by bolts or similar fastenings g, extending transversely through the I run from side to side.

In assembling the tire as in the draw ngs the coreis first inserted into the outer cas ng, and the core and casing are then moved into position encircling the felly or rim c, the tire being made slightly larger than the r1m to facilitate this operation; The annular strip 6 should then be inserted in sections between the core and the rim or felly, the inner edges of the casing d lying against the shoulders formed by the side e ges of the strip 6. After this has been done the clamps f are moved up bodily into position and held thereby the fastening-bolts g, which causes the wired inner edges of the casing d to be forcibly gripped between the clamps and the shoulders formed by "the side edges of the st r1p b. This securely holds all parts of the tire in place.

The peculiar form of the core w1th its roundin outer portion and ats contracted base an its cellular interior formation gives the core an exceedin ly high degree of resiliency, and the finishe tire 1s therefore almost as resilient as the pneumatic one. By means of the fastening effected by the coaction of the parts f and b with theoutercasing I am enabled to secure the tire in position in such a way that it will be practically impossible for it to be accidentally dislocated.

Various changes in the form, proportions, and minor details of my invention may be resorted to at will without de artm from the spirit and scope thereof. ence cons der myself entitled to all such variations as may 1 lie within the intent of my claims.

Having -thus described my invention, I claim as new and desire to secure by Letters Patent 1. In a vehicle-tire, the combination with therim or felly ofthe wheel, of an annular strip extending around the periphery of the rim and of less width than the rim forming two annular shoulders at the side portions thereof, an interior cushion gradually decreasin in thickness from its outer or periphera portion to its inner edges, and engaging at said edges the outer face of the strip and flush with the side edges thereof, a

' casing corres ending in elf-la e to the in tenor cushion, an also gradual y decreasing in thlckn ess from its outer or peripheral portion to the extreme inner edges thereof, the inner edges of the casing projecting inward beyond the contracted inneredges of the interior cushion and engaging the side edges of said strip and contact ng at theends with the outer eriphery of the rim, the contracted inyond the shoulders formed by the side edgesof the said strips, and means for holding the clamping-plates in place to cause the wired inner edges of the casing to be grip ed between the clamping-plates and the side edges of'said strips.

2. In a Vehicle-tire, the combination with I the rim or felly of the wheel,- of a strip extending around the periphery of the rim, and of less width than the rim forming an'annular shoulder extending around each side of the rim or folly, a casing decreasing 1n thickness from its outer or peripheral position to its ex c treme inner edges, the said contracted ed es.

being placed against said shoulders, annu ar .wires'emb-edded-in the inner contracted edges; of the casing atpoints opposite the said shoulders on the rim, annular clam ing-plates lying against the sides of the fe ly or rim and extending to points opposite.- said annular shoulders, the edges of said clampin-p'lates being enl'ar edand flared outward y, and.

means for olding the clamping -plates 111 place, to cause the wired inner edges of the casing to"be forcibly gripped between the clamping-plates and the sa d shoulders.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
